3 Claims. (c1. 131-198) This inventionrelates to tobacco smokingdevices, and its general purpose is to provide means for obtaining acontinuously cool, clean and dry smoke.

While the invention is subject to Wide application, it is of specialadvantage in pipes, cigarette and cigar holders, and the like. v

Common faults of conventional tobacco smoking deg Patented June 10, 1958ice v through for channeling smoke from the bowl to a mouthpiece 4fitted onto the opposite end of the stem. The stem may be attached tothe bowl in any suitable manner. Here, the end 5 of the stem is ttedinto a complementary bore 6 in a thickened base of the bowl. The smokepassage 3 of the stern opens through a radial port 10 which communicatesthrough a hole 13 in a partition wall 20 above to a burning chamber 30of the bowl. A short metal sleeve on the stem provides a radial'flange 8which abuts the outer face of the bowl about the opening 6.

A clean-out opening having a removable plug 9 is formed in the wall ofthe bowl directly opposite to and in axial alignment with the opening 6.A conventional cleaning probe may be inserted through the clean-outopening into the smoke passage 3 of the stem to free the latter' ofundesirable deposits.

vices are a hot smoke, dry throat, nicotinic and other deposits, andsmoke that it wet with tobacco juice. Now,

I have devised novel and improved means for eliminat-` ing these variousannoyances so as to make tobacco ysmoking a desirable and harmlesspleasure, I employ means wherebysmoke, passed from a smoking device tothe person is cool, clean and dry.

I provideV a clean and dry smoke-by filtering means of a novel nature; Iprovide a cool smoke by novel draft means whereby cooling air is adaptedto mix with the smoke.

A further feature of the invention is certain novel means whereby theVtemperature of the smoke issuing from a tobacco smoking device may beregulated from hot to-cool, as desired.

Accordingly, an object of this invention is to provide means; in tobaccosmoking devices for obtaining a cool, dry and cleansmoke.

Another object of the invention is to provide in a tobacco smokingdevice practical means for efliciently yfiltering the smoke of moisture,tobacco juices, and deposits; and to provide other practical andefficient means, adjustable for obtaining as desired a smoke of desiredtemperature.

A further object lof the invention is to obtain the foregoing benefitsin a practical manner, without weighty or cumbersome devices.

v'Ihe invention further lies in the particular structure aridarrangement of its component parts, as well as in their cooperativeassociation with one another to effect the results intended herein.

`',Ihe foregoing and other objects and advantages of this inventionwillv appear more fully hereinafter from a consideration ofthe detaileddescription which follows, taken together with the accompanying drawingslwhereinV an embodiment of the invention is illustrated. It is to be.expressly understood, however, that the drawings are for'"purposes'of'illustration and description, and are not to be construed asdefining the limits of the invention.

In the drawings:

Fig. 1 is an elevational view, partly in section, showing a pipe whereinthe invention is embodied;

Fig. 2 is a view of the pipe without the adjusting sleeve;

Fig. 3 is a view of the sleeve apart from the pipe;

Fig. 4 is la view of the sleeve rolled out at; and

Fig. 5 is a view of the stem rolled out flat.

There is shown in'the drawings a pipe having a bowl 1 for burningtobacco. To the bowl is attached one end of a cylindrical tubular stem 2having a passage 3 thereguished for lack of air.

The opposite end` of the stem is 'fitted with an end portion of a wood'or metal insert 11. TheV other end of the insert is fitted into themouthpiece 4. The insert provides a radial flange l2 which abuts theadjacent- The mouthpiece isA ingly, the stem is formed of moistureabsorption material which Will also act to filter yout impurities fromthe smoke. I have found lightweight wood having good absorptioncharacteristics as desirable for forming the stern member. Balsa wood isparticularly suitable for `this purpose, and therefore the stem is heremade of balsa wood. Balsa wood is rigid, yet light in weight. Itfunctions to not only absorb moisture from the smoke iiowing through thestem, but also acts to remove impurities from the smoke, such as,nicotinic deposits, andv other undesirable matter commonly found intobacco smoke. The stem may be made in Various lengths. I have, however,found that a stem of about three to ve inches in length gives excellentresults, as confirmed by the fact that smoke issuing from the mouthpieceis dry and clean,the moisture and impurities having been absorbed andfiltered out by the balsa wood stem.

To provide a cool as well as a clean and dry smoke, the stern isperforated with a plurality of pin holes 1d throughout its length,whereby the smoke is progressively cooled as it flows through thechannel and is mixed with cooling air entering the pin holes. The pinholes are of further advantage in that they provide a draft for' thebowl whereby the burning tobacco is not extin- This avoids theannoyance, so common with pipes, of having to repeatedly relight thetobacco.V

Some smokers prefer a cool smoke which will not dry their throats;others desire a smoke which is neither cool nor hot; while still otherslike a smoke in the condition in which it leaves the bowl, commonlycalled a hot smoke. To satisfy the tastes of each of these, anadjustable sleeve 15 formed of balsa wood is provided on the stem. Thesleeve and stem are provided with a particular pattern of pin holeswhereby the heat condition of the smoke may be'regulated so as to issuethrough the mouthpiece as desired from hot to cool,

The sleeve is rotatable on the stem to different angular positions, sothat in a first rotated position certain large pin holes 16 in thesleeve register with certain pin holes 17 in the stem, whereby air mixeswithv the smoke in the stem and provides a cool smoke. second rotatedposition of the sleeve certain other holes 18 in the sleeve of asmaller'size are registered withcertain other pin holes 19 in the stem,whereby less air mixes with the smoke and the issuing smoke is medium vcool. ln a third rotated position of the sleeve blank spaces in thesleeve seal over all the pin holes in the stem, whereby air to the smokepassage is cut o and the issuing smoke is conventionally hot. It is tobe noted that the pin holes in the stem are all of the same diameter.

A preferred form of pin hole arrangement or pattern in the sleeve andstem members is best shown in Figs. 4 and 5, wherein the sleeve and stemare respectively seen as rolled out flat.

The stem has four straight rows of pin holes, all of the same diameter.Each row is spaced 90 degrees from the next. The pin holes in each roware spaced onefourth inch apart. The alternate pin holes in the stem aredesignated 19, while the others are designated 17.

The sleeve member has eight straight rows of pin holes, four of whichcomprise the holes 16 and four of which comprise the holes 18. The rowscontaining holes 16 are spaced 9() degrees from each other; while therows containing the holes 18 are also spaced 90 degrees apart, but inalternate midway relation to the rows containing the holes 16. The holesin each of the several rows are spaced one-half inch behind each other.The starting position or location of the lirst hole in each rowcontaining the holes 1S is one-fourth inch inwardly from the initialposition of the first holes in the neighboring rows.

By this -arrangement or pattern of holes it can be seen that when thesleeve member is in its first or cool position, the pin holes 16 thereofwill register with the pin holes 17 in the stem; in its second or mediumcool position, the pin holes 18 of the sleeve will register Vwith thepin holes 19 of the stem. In its third or hot position, which will bebetween any of the other two positions, the blank spaces of the sleevewill seal over all the holes of the stem.

Where the sleeve and stem members are of sucient diameter, further pinhole sizes may be added to the sleeve for registration with added pinholes in the stem to provide furtherregulation of the temperature of thesmoke issuing from the mouthpiece.

Position indicating marks may be provided; such as a xed mark 21 on thebowl with which a mark 22 on the sleeve is alignable to indicate thecool position; and a mark 23 is alignable to indicate the medium coolposition.

While an embodiment of the invention has been illustrated and describedin detail, it is to be expressly understood that the invention is notlimited thereto. Various changes can be made in the design andarrangement of the parts without departing from the spirit and scope ofthe invention, as the same will now be understood by those skilled inthe art; and it is my intent, therefore, to claim the invention not onlyas shown and described, but also in all such forms and modifications ascan reasonably be construed to fall within the spirit of the inventionand the scope of the appended claims.

In another or What is claimed is:
